Oscar®-winning actor David Niven stars as a millionaire with two bored grandchildren who fake their own kidnapping, holding themselves for ransom! In cahoots with the kids is a pair of down-on-their-luck burglars (Darren McGavin and Don Knotts). It doesn't take long for the two young pranksters to discover just how impractical a practical joke can be. The mayhem escalates into an all-out cops-and-robbers chase filled with every bit as much hilarity as excitement.
